From two people to 300 installs a month
This is how our Danish installation team scaled AirPro — and the five systems we hand to partners who want to do the same. The seeds are on this page. The rest we build with you.

The three phases every partner goes through
The product is the easy part. What separates a partner doing ten installs a month from one doing three hundred is not the drill — it is what happens before and after the install.
Phase 1 · months 0–6
Solo installer
You are sales, installer and admin
One van, a product that installs in under an hour, and a phone that has to be answered fast. The goal is a repeatable install and a price you can quote without a site visit. Most partners reach two to three installs a day here.
Phase 2 · months 6–12
First hire
Half sales, half installing
More enquiries than you can handle is the signal. You train your first technician and the bottleneck moves from installing to answering, quoting and following up. This is where systems replace effort.
Phase 3 · months 12–24
Full team
You stop installing
A team of three to five, a fleet, and a calendar that fills itself. You run sales, hiring and the numbers — not the drill. This is where our own team operates today, and the systems below are what got us there.
Who this is built for
Our strongest partners did not come from ventilation. They came from trades that were already inside people’s homes with the right tools — and added AirPro as a new revenue line.
HVAC & ventilation companies
The jobs you turn away today are the most profitable ones we do.
Flats, single rooms, retrofits where ducting is impossible. Same crew, same skills, under an hour per unit — at a margin per hour your central systems rarely match.
Electricians & plumbers
You already have the customer's trust and a drill. Now you have a product.
AirPro plugs into a normal socket. No extra trade on site, no permits, no ductwork. It is a product with margin on top of the hours you already sell.
Core-drilling & renovation crews
You can already do 80% of an AirPro install.
The hole is the hard part, and you do that every day. We teach you the last 20% — mounting, sealing, commissioning — and where the customers come from.
Heat-pump & solar installers
Indoor air is the other half of an energy-efficient home.
Damp, condensation and mould are winter problems. AirPro gives you something to sell to your existing customers in the months when the phone is quiet.
Distributor or wholesaler without an installation team? Our model is built around installers, but we do work with selected distributors — contact us here instead.
The five systems that do the work
We built these for our own installation business first. They run on automation and AI, and they are the reason a small team can handle a large calendar. Partners get them — set up, not described.
01
The lead machine
Paid campaigns on Meta and Google, built around the problems homeowners actually search for: damp, condensation, mould, stale air. Landing pages per problem, not per product.
What partners get
We hand you the campaign structure, the creatives and the landing pages that work for us — adapted to your market and your brand.
02
AI-qualified enquiries
An AI assistant on your website and social channels that answers first, asks the right questions (rooms, wall type, basement, photos) and turns a curious visitor into a lead you can quote without a site visit.
What partners get
Trained on thousands of real AirPro conversations. Your brand on the front, our knowledge underneath.
03
Follow-up that never forgets
Every enquiry lands in a pipeline. Quotes go out the same day, reminders go out automatically by SMS and email, and nothing goes cold because someone was on a roof.
What partners get
A ready-made CRM setup with the sequences we use ourselves — you get the structure, we help you switch it on.
04
Content and video on demand
Short videos, before-and-after images, ad variations and social posts — produced with AI tooling in days, not weeks. Fresh creative is what keeps campaign costs down.
What partners get
A content library for your market that you can put your logo on, plus the process for making more.
05
Numbers you can steer by
Cost per enquiry, quote-to-install rate, gross profit per install, break-even per month. Five numbers decide whether you hire the next technician.
What partners get
A simple partner dashboard and the unit-economics model from our Partner Guide, pre-filled for AirPro.

What you will want to know before you say yes
Every serious partner asks the same ten questions. Here are nine of them. The tenth is pricing — and we explain below why that one is a conversation.
Certifications
CE, ErP, CB and RoHS. Test documentation is shared with partners after the first call.
Warranty & after-sales
Manufacturer warranty on every unit, a technical hotline, spare parts from Denmark and a step-by-step troubleshooting library.
Minimum order
None to start. Most partners begin with a demo unit. Stock ships on half pallets (12 units) or full pallets from Denmark.
Delivery
Pallet shipments across Europe, lead times confirmed per country on the call.
Exclusivity
Regional protection while you build your market. Long-term exclusivity is earned on volume, not promised up front — we say that openly.
Training
Product and installation certification, with the option to train hands-on with our own crew in Denmark.
Marketing material
Datasheets, brochures, images, video and ad creatives in your language, ready for your logo.
Partners in my country
25+ partners across Europe today. Most countries still have open regions — ask on the call.
Pricing
Partner pricing depends on your market and volume, so we go through it on the Scale Call rather than posting a list. No games — you get the full sheet the same day.
Personal coaching
This is not theory. It has been done.
Casper Søndergaard, founder of Din Ventilation, built the systems on this page while scaling a Danish installation business from 8 to 30 people in 18 months — 300+ AirPro installs a month, Craftsman of the Year 2026, and 4.7 out of 5 from more than 550 customer reviews. Every system was proven on real jobs before it was offered to a partner.
Partners who want to go further than the product can work with Casper directly: personal coaching on sales, hiring, numbers and mindset for owners who are serious about growth. It is not for everyone, and it is not the first step — the free Scale Call is.

Straight answers
Do you deliver leads to partners?
We deliver the lead machine, not a list. Our own team receives hundreds of enquiries a month from the exact system we set up with you, running in your market and under your brand. You own the results.
Do I need an electrician or ventilation licence?
No. AirPro V2 ships with a 5 m cord and a standard plug, and installs through one core-drilled hole. If you are confident with a diamond core drill, you can install it. Training covers the rest.
Is there a minimum order?
Not to start. Most partners begin with a demo unit, then order by half or full pallet once they are installing.
What does the Scale Call cost?
Nothing. It is a conversation about your business. Setup packages are only quoted afterwards, and only if we both think it makes sense.
Is my region still open?
Most of Europe is. We protect the regions of active partners, so apply before someone else in your area does.
